Introducing new chicks to pullets

[Albanese07]

I have a barred rock and a rhode island red 6 1/2 weeks old almost fully feathered in the coop last weekend. Today at the feed store I bought 2 more rhode island reds, about a week old. When they get big enough how do I introduce them? Do I just put them in the coop and pray for the best? Any advice is appreciated! Thanks!

Can you coop or run be divided? If so, when the new chicks get about four weeks old put them in one part and let them all get used to each other. After a a couple weeks more allow them to interact with as much room as you can
